Anyone know what these are and how to use them?  I tried hosting an area load to a slab, but it didn't show up in the schedule i created.  I am confused as to what these are, and how to create them...

Thanks.

I am guessing that you are using Revit Structure. These loads are for transfer to Analysis Programs.

I understand the need to transfer to Analysis Programs.  But what are the schedules in revit for then.  Is the work flow then to bring the line load data back into Revit somehow to populate the schedules?

Rather than input design criteria such as roof live loads, floor dead loads, etc. into my construction documents as 'dumb' text, I had thought to create shared attributes and disseminate the data using the real power behind BIM.  But after creating the attributes and the schedules, I am not sure how populate them with the appropriate data.

I have been using Revit Architecture for years until recently.  Any guidance in this aspect of Revit Structure would be greatly appreciated.

Thanks,

This is probably too late to help you but it might be useful for someone with the same question... Internal loads are imported into Revit from analysis software, i.e. Robot Structural Analysis. I don't think it is possible to create internal loads directly in Revit. The link between Revit and Robot is accessed from within Revit (Analyze tab) and provides an option to "update" the Revit model using data in the Robot model. If the option to transfer results is selected; the Revit will import the Fx, Fy, Fz, Mx, My and Mz values for each member into Revit within the internal forces category. These can then be scheduled in the normal way. The only problem is that there does not seem to be a straight-forward way of linking the physical model attributes (i.e. family, type, length, etc.) to the internal loads in the schedule which makes the schedule fairly unless. I'm sure a work around could be figured out, such as using the comment parameter to filter which forces should and should not be displayed in the schedule or possibly using custom parameters.

Hope that makes sense!
